>>>Well, it's clearly due to that special build process you're using, Torgny. I didn't run it, I just did a search for relevant utilities when you described what you were doing, and made an educated guess.

>>>When I look at the code it seems okay, but clearly there is something wrong with it. Can you tell me more about how you're using it?
>>>
>>>Can you also tell me whether you have this problem no matter which version of VFP you build under?
>>>
>>>If we can come up with steps to repro, you will want to post a bug, even if it is just a request for a revision of that MSDN article.
>>>
>>>I don't have time to run the code this morning and if I did I might not see the exact scenario that you do, so I'd appreciate it if you take a crack at narrowing down the issue first, but I will check this with you later.
